When you think about it nearly every pop song is about love in some form or another. Most songs on the topic are either about celebrating being in love or alternately mourning falling out of love and wanting to get back there. Of the literally millions of songs on love I think John Lennon wrote and recorded some of the most touching and poignant ones - two of which I have included here on this Valentine's Day. Above is "Oh My Love" with Lennon on piano and George Harrison joining him on guitar. The song was written by John Lennon with Yoko Ono and first appeared in 1971 on Lennon's album Imagine on which George Harrison contributed to several songs in addition to this one. "Oh My Love" can also be found on Wonsaponatime: Selections from Lennon Anthology

Then below is the simple but powerful Lennon song "Love" (with lyrics in the video) that was first released on the 1970 album John Lennon/Plastic Ono Band. As anyone who has that album knows the piano part at the beginning (and end) is really quiet but builds in volume. So you will notice that the version below is the later remix of the song with the sound levels more equalized on these two parts. The posthumous version of "Love" below appeared a dozen years after the initial release on the 1982 compilation The John Lennon Collection, and later appeared on such other collections as the John Lennon Anthology box set.
